実用新案登録第３０８３７４７号公報（第２図）Utility Model Registration No. 3083747 (Fig. 2) 特開２００７−２００６９６号公報JP-A-2007-2000866 特開２０１７−７３３００号公報JP-A-2017-73300

特許文献１の場合、締付部材の下部と電線との間にケーシング部材が挟まれる。電線は、締付部材の上部の内側で動き得る。このため、ケーシング部材が締付部材によって電線側に押し付けられる状態を形成しにくい。その結果、締付部材の下部とケーシング部材との間に隙間が生じる懸念がある。仮に、締付部材の下部とケーシング部材との間に隙間が生じると、ケーシング部材およびカバーが位置ずれするおそれがある。 In the case of Patent Document 1, the casing member is sandwiched between the lower part of the tightening member and the electric wire. The wire can move inside the top of the tightening member. Therefore, it is difficult to form a state in which the casing member is pressed against the electric wire side by the tightening member. As a result, there is a concern that a gap may be created between the lower part of the tightening member and the casing member. If a gap is created between the lower part of the tightening member and the casing member, the casing member and the cover may be misaligned.

そこで、締付部材によってカバーの位置ずれを防止することが可能なコネクタを提供することを目的とする。 Therefore, it is an object of the present invention to provide a connector capable of preventing the position shift of the cover by the tightening member.

本開示のコネクタは、電線が引き出されるコネクタハウジングと、前記電線を被覆する本体カバーおよび蓋カバーと、前記本体カバーの面部に沿って巻き付けられる締付部材と、前記本体カバーの面部に周方向に間隔を隔てて設けられる第１部位および第２部位と、前記本体カバーにおいて、前記第１部位と前記第２部位との間に設けられる凹部と、前記締付部材において、前記第１部位から前記第２部位に向けて架け渡される押さえ部と、前記蓋カバーにおいて、前記凹部に受けられる連結部と、前記連結部において、前記第１部位と前記第２部位とを結ぶ仮想直線の外側に配置され、前記押さえ部によって前記凹部の内面側に押し付けられる被押圧部と、を備える。 The connectors of the present disclosure include a connector housing from which an electric wire is pulled out, a main body cover and a lid cover that cover the electric wire, a tightening member that is wound along a surface portion of the main body cover, and a circumferential direction around the surface portion of the main body cover. The first portion and the second portion provided at intervals, the recess provided between the first portion and the second portion in the main body cover, and the tightening member from the first portion to the said. The holding portion that is bridged toward the second portion, the connecting portion that is received by the recess in the lid cover, and the connecting portion that is arranged outside the virtual straight line that connects the first portion and the second portion. It is provided with a pressed portion that is pressed against the inner surface side of the recess by the pressing portion.

本開示によれば、締付部材によってカバーの位置ずれを防止することが可能なコネクタを提供することが可能となる。 According to the present disclosure, it is possible to provide a connector capable of preventing the misalignment of the cover by the tightening member.

［本開示の実施形態の説明］
最初に本開示の実施態様を列記して説明する。
本開示のコネクタは、
（１）電線が引き出されるコネクタハウジングと、前記電線を被覆する本体カバーおよび蓋カバーと、前記本体カバーの面部に沿って巻き付けられる締付部材と、前記本体カバーの面部に周方向に間隔を隔てて設けられる第１部位および第２部位と、前記本体カバーにおいて、前記第１部位と前記第２部位との間に設けられる凹部と、前記締付部材において、前記第１部位から前記第２部位に向けて架け渡される押さえ部と、前記蓋カバーにおいて、前記凹部に受けられる連結部と、前記連結部において、前記第１部位と前記第２部位とを結ぶ仮想直線の外側に配置され、前記押さえ部によって前記凹部の内面側に押し付けられる被押圧部と、を備える。この構成によれば、締付部材が本体カバーの面部に沿って巻き付けられる。締付部材の押さえ部が第１部位から第２部位に向けて架け渡される。これにより、連結部の被押圧部が凹部の内面側に押し付けられる。この場合に、連結部の被押圧部が第１部位と第２部位とを結ぶ仮想直線の外側に配置されるため、連結部が凹部の内面側に強く押し付けられる。その結果、連結部が凹部の内面側に対して位置ずれしにくくなり、ひいては本体カバーおよび蓋カバーの位置ずれを効果的に防止することができる。 [Explanation of Embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
The connectors of the present disclosure are
(1) A connector housing from which an electric wire is pulled out, a main body cover and a lid cover that cover the electric wire, a tightening member that is wound along a surface portion of the main body cover, and a peripherally spaced space around the surface portion of the main body cover. In the main body cover, the recesses provided between the first part and the second part, and in the tightening member, the first part to the second part are provided. It is arranged outside the virtual straight line connecting the first part and the second part in the holding part, the connecting part received in the recess in the lid cover, and the connecting part. It is provided with a pressed portion that is pressed against the inner surface side of the recess by the pressing portion. According to this configuration, the tightening member is wound along the surface portion of the main body cover. The pressing portion of the tightening member is bridged from the first portion to the second portion. As a result, the pressed portion of the connecting portion is pressed against the inner surface side of the recess. In this case, since the pressed portion of the connecting portion is arranged outside the virtual straight line connecting the first portion and the second portion, the connecting portion is strongly pressed against the inner surface side of the recess. As a result, the connecting portion is less likely to be misaligned with respect to the inner surface side of the recess, and thus the misalignment of the main body cover and the lid cover can be effectively prevented.

（２）前記第１部位を上向きにとした場合に、前記第１部位は、前記被押圧部よりも高い位置に配置され、前記押さえ部は、前記第１部位から前記被押圧部にかけて下向きに傾斜して配置されるのが好ましい。この構成によれば、連結部の被押圧部が締付部材の押さえ部によって凹部の内面側に一層強く押し付けられる。このため、本体カバーおよび蓋カバーの位置ずれを防止する信頼性を高めることができる。 (2) When the first portion is directed upward, the first portion is arranged at a position higher than the pressed portion, and the pressing portion is downward from the first portion to the pressed portion. It is preferably arranged at an angle. According to this configuration, the pressed portion of the connecting portion is pressed more strongly toward the inner surface side of the recess by the pressing portion of the tightening member. Therefore, it is possible to improve the reliability of preventing the displacement of the main body cover and the lid cover.

（３）前記凹部は、前記連結部を支持する支持面と、前記連結部の一側面に対向する受け面と、前記支持面と前記受け面との交差部分に位置する内角部と、を有し、前記被押圧部は、前記内角部と対角する位置に配置されると良い。この構成によれば、連結部の被押圧部が締付部材の押さえ部によって凹部の内角部に向けて押し付けられる。このため、本体カバーおよび蓋カバーの位置ずれを防止する信頼性を一層高めることができる。 (3) The recess has a support surface that supports the connecting portion, a receiving surface that faces one side surface of the connecting portion, and an internal angle portion that is located at an intersection of the supporting surface and the receiving surface. However, it is preferable that the pressed portion is arranged at a position diagonal to the inner corner portion. According to this configuration, the pressed portion of the connecting portion is pressed toward the inner corner portion of the recess by the pressing portion of the tightening member. Therefore, the reliability of preventing the displacement of the main body cover and the lid cover can be further improved.

（４）前記本体カバーの面部は、周方向に間隔を隔てて設けられる第３部位および第４部位を有し、前記本体カバーは、前記第３部位と前記第４部位との間に、前記電線を受ける電線側凹部を有し、前記締付部材は、前記第３部位から前記第４部位に向けて架け渡され、前記電線を前記電線側凹部の内面側に押し付ける電線固定部を有していると良い。この構成によれば、本体カバーの面部が連結部および電線を受ける領域として有効に活用され、本体カバーの小型化に寄与することができる。 (4) The surface portion of the main body cover has a third portion and a fourth portion provided at intervals in the circumferential direction, and the main body cover is formed between the third portion and the fourth portion. It has an electric wire side recess that receives an electric wire, and the tightening member has an electric wire fixing portion that is bridged from the third portion toward the fourth portion and presses the electric wire to the inner surface side of the electric wire side recess. It is good to have it. According to this configuration, the surface portion of the main body cover is effectively utilized as an area for receiving the connecting portion and the electric wire, and can contribute to the miniaturization of the main body cover.

Therefore, the operator picks the tip of the band 65 through the opening 56, and runs the tip of the band 65 from the outer surface of the other side wall 26 on the face 33 to the lower surface of the bottom wall 23. The tip of the band portion 65 is inserted below the bottom wall 23 into the locking hole 66 of the base portion 64 from above. The operator picks the tip of the band portion 65 that has passed through the locking hole 66 and pulls it downward. As a result, the locking teeth 68 of the band portion 65 are locked to the locking projections 67 in the locking holes 66 in a state where the band portion 65 is in close contact with the surface portion 33 in the circumferential direction.

バンド部６５の電線固定部６９は、第３部位３９と第４部位４０との間に、各電線９０を電線側凹部３５の湾曲状の内面に押し付けた状態で、架け渡して配置される（図３を参照）。電線固定部６９は、各電線９０のうち、電線側凹部３５の内面の内奥から最も離れた電線９０の外周に接する。このため、電線固定部６９は、各電線９０に対して電線側凹部３５の内奥へ向けて押し付け力を付与することができる。各電線９０は、電線固定部６９の押し付け力を受け、電線側凹部３５に固定される。 The electric wire fixing portion 69 of the band portion 65 is arranged so as to be bridged between the third portion 39 and the fourth portion 40 in a state where each electric wire 90 is pressed against the curved inner surface of the electric wire side recess 35 (the electric wire fixing portion 69). See FIG. 3). The electric wire fixing portion 69 is in contact with the outer circumference of the electric wire 90 farthest from the inner inner surface of the electric wire side recess 35 among the electric wires 90. Therefore, the electric wire fixing portion 69 can apply a pressing force to each electric wire 90 toward the inner depth of the electric wire side recess 35. Each electric wire 90 receives the pressing force of the electric wire fixing portion 69 and is fixed to the electric wire side recess 35.

バンド部６５の押さえ部６２は、第１部位３７と第２部位３８との間に、連結部５９を凹部３４の内面に押し付けた状態で、架け渡して配置される（図３および図９を参照）。押さえ部６２は、連結部５９において凹部３４の内角部４３と対角する位置にある被押圧部６３に接する（図９を参照）。 The holding portion 62 of the band portion 65 is arranged so as to be bridged between the first portion 37 and the second portion 38 with the connecting portion 59 pressed against the inner surface of the recess 34 (FIGS. 3 and 9). reference). The pressing portion 62 is in contact with the pressed portion 63 at a position diagonal to the inner corner portion 43 of the recess 34 in the connecting portion 59 (see FIG. 9).

具体的には、押さえ部６２は、被押圧部６３に接する部位を頂部７０とし、第１部位３７から被押圧部６３にかけて下向きに傾斜し、被押圧部６３から第２部位３８にかけてより急角度で下向きに傾斜して配置される。言い換えれば、連結部５９の被押圧部６３および押さえ部６２の頂部７０は、第１部位３７と第２部位３８とを直線状に結ぶ仮想直線（図９の一点鎖線ＶＬ）の外側に配置される。このため、押さえ部６２は、連結部５９に対して凹部３４の内角部４３へ向けて押し付け力を付与することができる。連結部５９は、押さえ部６２の押し付け力を受け、凹部３４に固定される。こうして連結部５９が凹部３４に安定して固定されることにより、本体カバー１１に対する蓋カバー１２の位置ずれが規制される。その結果、カバー部材内における各電線９０の挿通領域が規定され、各電線９０がコルゲートチューブ１４の内面に当たるのを防止することができる。各電線９０がコルゲートチューブ１４の内面から離れて配置されることで、各電線９０およびコルゲートチューブ１４の損傷を防止することができる。 Specifically, the pressing portion 62 has a portion in contact with the pressed portion 63 as the top portion 70, is inclined downward from the first portion 37 to the pressed portion 63, and has a steeper angle from the pressed portion 63 to the second portion 38. It is arranged so that it tilts downward. In other words, the pressed portion 63 of the connecting portion 59 and the top 70 of the pressing portion 62 are arranged outside the virtual straight line (one-dot chain line VL in FIG. 9) that linearly connects the first portion 37 and the second portion 38. To. Therefore, the pressing portion 62 can apply a pressing force to the connecting portion 59 toward the inner corner portion 43 of the recess 34. The connecting portion 59 receives the pressing force of the pressing portion 62 and is fixed to the recess 34. By stably fixing the connecting portion 59 to the recess 34 in this way, the displacement of the lid cover 12 with respect to the main body cover 11 is regulated. As a result, the insertion region of each electric wire 90 in the cover member is defined, and it is possible to prevent each electric wire 90 from hitting the inner surface of the corrugated tube 14. By arranging each electric wire 90 away from the inner surface of the corrugated tube 14, damage to each electric wire 90 and the corrugated tube 14 can be prevented.

以上説明したように、本実施形態によれば、連結部５９の被押圧部６３が仮想直線ＶＬの外側に配置されるため、連結部５９が凹部３４の内面側に強く押し付けられる状態を実現することができる。その結果、連結部５９が凹部３４の内面側に対して位置ずれしにくくなり、ひいては本体カバー１１および蓋カバー１２の相互の位置ずれを効果的に防止することができる。 As described above, according to the present embodiment, since the pressed portion 63 of the connecting portion 59 is arranged outside the virtual straight line VL, a state in which the connecting portion 59 is strongly pressed against the inner surface side of the recess 34 is realized. be able to. As a result, the connecting portion 59 is less likely to be misaligned with respect to the inner surface side of the recess 34, and thus the misalignment of the main body cover 11 and the lid cover 12 can be effectively prevented.

ここで、第１部位３７は、仕切部３６の上面に設けられ、被押圧部６３より高い位置に配置される。押さえ部６２は、第１部位３７から被押圧部６３にかけて下向きに傾斜して配置される。よって、連結部５９が凹部３４の内角部４３側に一層強く押し付けられる。その結果、本体カバー１１および蓋カバー１２の位置ずれを防止する信頼性を高めることができる。 Here, the first portion 37 is provided on the upper surface of the partition portion 36 and is arranged at a position higher than the pressed portion 63. The pressing portion 62 is arranged so as to be inclined downward from the first portion 37 to the pressed portion 63. Therefore, the connecting portion 59 is pressed more strongly toward the inner corner portion 43 side of the recess 34. As a result, the reliability of preventing the displacement of the main body cover 11 and the lid cover 12 can be improved.

また、面部３３は、仕切部３６を介して、凹部３４および電線側凹部３５を有している。連結部５９は、凹部３４に受けられる。各電線９０は、電線側凹部３５に受けられる。その状態で、締付部材１３が被締結部２２に締め付けられることにより、連結部５９および各電線９０が被締結部２２に固定される。このように、面部３３が連結部５９および電線９０を受ける領域として有効に活用されることにより、本体カバー１１の小型化に寄与することができる。 Further, the surface portion 33 has a recess 34 and a recess 35 on the electric wire side via the partition portion 36. The connecting portion 59 is received by the recess 34. Each electric wire 90 is received by the electric wire side recess 35. In this state, the tightening member 13 is tightened to the fastened portion 22, so that the connecting portion 59 and each electric wire 90 are fixed to the fastened portion 22. As described above, the surface portion 33 is effectively utilized as a region for receiving the connecting portion 59 and the electric wire 90, which can contribute to the miniaturization of the main body cover 11.
